commit ec1aab7816b06c32f42935e34ce3a3040c778afb upstream.
This uses more aggressive hueristics than the the bootup default
profile. On windows the OS has a special fullscreen 3D mode
where this is used. Since we don't have the equivalent on Linux
default to this profile for dGPUs.

commit ab0d6ef864c5fa820e894ee1a07f861e63851664 upstream.
xe_gt_enable_host_l2_vram() is reading the XE2_GAMREQSTRM_CTRL register
that is currently missing the MCR annotation. However, just adding the
annotation doesn't work as this function is called before MCR handling
is initialized in xe_gt_mcr_init().
xe_gt_enable_host_l2_vram() is used to implement WA 16023588340 that
needs to be done as early as possible during initialization in order to
be effective since the MMIO writes impact it. In the failure scenario,
driver would simply not be able to bind successfully.
Moving xe_gt_enable_host_l2_vram() later, after MCR initialization is
done, only incurs a few additional HW accesses, particularly when
loading GuC for hwconfig. Binding/unbinding the driver 100 times in BMG
still works so it should be ok to start handling the WA a little bit
later. This is sufficient to allow adding the MCR annotation to
XE2_GAMREQSTRM_CTRL.

commit 014125c64d09e58e90dde49fbb57d802a13e2559 upstream.
Setting 'nomodeset' on the kernel command line disables all graphics
drivers with modesetting capabilities, leaving only firmware drivers,
such as simpledrm or efifb.
Most DRM drivers automatically support 'nomodeset' via DRM's module
helper macros. In xe, which uses regular module_init(), manually call
drm_firmware_drivers_only() to test for 'nomodeset'. Do not register
the driver if set.
v2:
- use xe's init table (Lucas)
- do NULL test for init/exit functions

an infoframes.enable mismatch issue which is caused when pipe is

eDp's post ddi disable routine does not clear infoframes.enable VSC

[ Upstream commit 071b24b54d2d05fbf39ddbb27dee08abd1d713f3 ]
Commit d469647bafd9 ("Input: simplify event handling logic") introduced
code that would set handler->events() method to either
input_handler_events_filter() or input_handler_events_default() or
input_handler_events_null(), depending on the kind of input handler
(a filter or a regular one) we are dealing with. Unfortunately this
breaks cases when we try to re-register the same filter (as is the case
with sysrq handler): after initial registration the handler will have 2
event handling methods defined, and will run afoul of the check in
input_handler_check_methods():
input: input_handler_check_methods: only one event processing method can be defined (sysrq)
sysrq: Failed to register input handler, error -22
Fix this by adding handle_events() method to input_handle structure and
setting it up when registering a new input handle according to event
handling methods defined in associated input_handler structure, thus
avoiding modifying the input_handler structure.

[ Upstream commit 3e8b7238b427e05498034c240451af5f5495afda ]
The gpiolib debugfs interface exports a list of all gpio chips in a

The gpio chip sections are supposed to be separated by a newline
character, but a long-standing bug prevents the separator from
being included when output is generated in multiple sessions, making the
output inconsistent and hard to read.

[ Upstream commit fe05cee4d9533892210e1ee90147175d87e7c053 ]
Short circuiting TDR on jobs not started is an optimization which is not
required. On LNL we are facing an issue where jobs do not get scheduled
by the GuC if it misses a GGTT page update. When this occurs let the TDR
fire, toggle the scheduling which may get the job unstuck, and print a
warning message. If the TDR fires twice on job that hasn't started,
timeout the job.
v2:
- Add warning message (Paulo)
- Add fixes tag (Paulo)
- Timeout job which hasn't started after TDR firing twice
v3:
- Include local change
v4:
- Short circuit check_timeout on job not started
- use warn level rather than notice (Paulo)

[ Upstream commit 993ca0eccec65a2cacc3cefb15d35ffadc6f00fb ]
On LNL without a mmio read before a GGTT invalidate the GuC can
incorrectly read the GGTT scratch page upon next access leading to jobs
not getting scheduled. A mmio read before a GGTT invalidate seems to fix
this. Since a GGTT invalidate is not a hot code path, blindly do a mmio
read before each GGTT invalidate.

Empirically we can confirm that the former allocates 152 bytes for the
table, while the latter memsets the 168 large block.
Root cause appears that when GPU metrics tables for v2_4 parts were added
it was not considered to enlarge the table to fit.
The fix in this patch is rather "brute force" and perhaps later should be
done in a smarter way, by extracting and consolidating the part version to
size logic to a common helper, instead of brute forcing the largest
possible allocation. Nevertheless, for now this works and fixes the out of
bounds write.

[ Upstream commit 48f62d38a07d464a499fa834638afcfd2b68f852 ]
In order to ensure root CXL ports are enabled upon cxl_acpi_probe()
when the 'cxl_port' driver is built as a module, arrange for the
module to be pre-loaded or built-in.
The "Fixes:" but no "Cc: stable" on this patch reflects that the issue
is merely by inspection since the bug that triggered the discovery of
this potential problem [1] is fixed by other means. However, a stable
backport should do no harm.
Fixes: 8dd2bc0f8e02 ("cxl/mem: Add the cxl_mem driver")
